automatic scrolling a field to the bottom when Text is entered

   Rather than bother with the field's formatted height, why not just use 
"select character (1 + the length of field FRED) of field FRED" or "select 
after the last character of field FRED" instead? Sounds to me like an oldText 
property plus "send to me in X seconds" really is the way to go for what you 
want; if the time it took to mess with formatted height was the problem, 
"select after the last character" should hopefully be a solution.
   Hope this helps...
